BOX-TOE M,ATERIAL FOR FOOTWEAR.

Specification of Letters Patent. Patented Sept. 19, 1915.

Application filed May' 6, 1916. Serial No. 95,793.

To all whom it may concern.-

Be it known that I, GEORGE FREYTAG, a citizenof the United States,residingat San Francisco, in the county of San Francisco, have inventeda new of which the following is a specification in such full and clearterms as will enable those skilled in the art to construct and use thesame.

This invention relates to a box toe material for footwear, the object ofwhich is to produce a felt, cloth, cloth and paper or cloth and leatherbox toe, which will retain its shape better than the ordinary leatherbox toes used for that purpose, and which will not be so easily affectedby changes in temperature and moisture as will the leather box toes.

' absorb water so readily as leather toes.

An embodiment of the invention is shown in the drawing in which the samereference numeral is applied to the same portion throughout, but I amaware that there may be many modifications thereof.

Figures 1 to 4 are plan views of the several parts of the box toe beforethey are secured together, Fig. 5 is a plan view of a completed toeready for forming, Figs. 6 to 9 are plan views of slightly differentlyshaped pieces of material for making a box toe, Fig. 10 is a plan Viewof the completed toe ready for forming, and Fig. 11 is a ver- Fig. 5. V

The numeral 1 indicates a more or less semi-circular piece of cloth, 2 aslightly smaller piece of cloth of the same general shape, 3a'semi-circular piece of clothsmaller the other two and 4 a piece ofcard board or other heavy .material intended to give stiffness to theother'.portions of the finished box toe.

It will be understood that while the term cloth is used herein withrespect to the I several parts of the toe that a suitable felt might beused in place of the cloth, and for stiffening material either felt,cloth, paper or leather could be used.

An insoluble paste consisting of one POHIlCl of casein to two ounces oflime is i then mixed up and the several parts of the toe are impregnatedsuccessively with said Another object of the invention is to produce asubstitute for leather which will not paste. At first the large cloth 1is impregnated with the paste; after that the small cloth 3 isimpregnated with the paste and secured to the first one. Following thisthe stiifening material a is covered with the paste and secured to themember 3, after which the large member 2- is then pasted on the otherparts.

It will be observed that none of the four parts going to make up the boxtoe are exactly the same size, the object being to cause the toe form totaper out atthe edges as thin as possible and to make as smooth afinished product as possible. here very small shoes are made it may befeasible to dispense with the stifi'ening material a and only use acloth suitably reinforced with smaller pieces and impregnated with thepaste.

I In Figs. 6, 7, 8 and 9 there is shown a slightly differently shapedseries of cloths used for completing the toe. In these figures thenumeral 6 indicates the larger cloth, 7 a slightly smaller one, 8 a muchsmaller cloth and 9 a piece of card board used for a stifiening materialand having ends 10 and 11 which project substantially the entire widthof the larger'pieces of cloth.

It will be understood that while only two shapes have been shown thattheparticular shape of the felt pattern is a matter that is dependententirclyupon the desired shape of the finished box toe and is notmaterial to the scope of the invention.

After the several layers of fabric, felt, leather or paper aresecuredtogether with the casein paste they are dried and are ready to beformed up into the desired shape for the finished footwear. While thecasein is not soluble in water the fiat box toe material may be'softened by placing it in hot or cold water and allowing it to soak fora consid; erable time, after which the material is formedup andstretchedintoihe desired shape and when Having thus described invention what Iclaim as',new and desire to secure by Letters Patent of the UnitedStates, is as follows, express reservation being madeof per; missiblemodifications:

1. box toe material for footwear consisting of layersof fabricimpregnated with a sblution .oi casein and lime.

2::"A box'toeniater-ial for-footwear conagain dried will retain thatshape indefinitely.

sistin of several layers of cloth im )re ringed with casein and lime.

A box toe material consisting of several layers of cloth, a layer ofstifi'eningbe- 5 tween the cloth layers, the series of layers beingimpregnated with a solution of casein and lime.

4. A box toe material consisting of a plurality of layers of cloth witha layer 10 of stifi'ening 1 material between the cloth layers, theentire series being impregnated with a paste of casein and lime.

5. A box toe material consisting of EL plurality of layers of cloth, athickness of paper between the layers of cloth, and a solution of caseinand lime impregnating the several 1 layers of cloth and paper.

In testimony whereof I have hereunto set my hand this 29th day of AprilA. D. 1916.

GEORGE FREYTAG.
